FILLING-END cnnannn.

Application filed October 21, 1926. serial No. 143,223. r

My invention relates to improvements in looms and more particularly to means for withdrawing the trailing end of the old filling from the shuttle when replenishment has been effected, a

In looms of the filling replenishin ty e sometimes called automatic looms, the fill ing is replenished from time to time by substituting for the old filling, carrier or bobbin in the shuttle, anothercontaining a su ply of filling wound thereon. When the til ing is replenished it is the usual practice to part the old fillin between the clothsel- ,vage and shuttle, i it be not withdrawn when the filling carrier or bobbin is ejected, it is likely that it will be carried into and produce a defective portion in the, cloth.

An important object of my invention is to provide means for withdrawing and holding the filling end.

Another ob ect of my invention is the provision of a device of this character which will be automatic and positive in action and i which will. be simple of construction and operation. y

Other objects and advantages of my invention will be a parent during the course of the following escription.

In the accompanyin drawings which form a part of this s eci cation an wherein like characters of re erence denote like parts throughout the same,

Figure 1 is a perspective view of the replenishing side portion of a filling replenishmg loom having the resent invention associated therewith, the 00111 portions being 1l- V lustrated in dotted lines and the attachment being shown in its inoperative osition,

Figure 2 is a side elevation o my invention in its operative position, and,

Figure 3 is a similar view of the invention after operation, the filling end being held by the invention.

In the drawings, wherein for thepurse of illustration is shown a preferred one of my invention, the numeral designatesthe loom frame upon which is mounted the bracket 11 for supporting the hopper or battery 12 containing the filling carriers or bobbins to be transferred. Extending from the bracket 12 is the stud or fixed transferrer shaft 13 on which is mounted the usual transferring mechanism 14 for transferring filling carriers or bobbins 15 from the hopper to the shuttle on callforreplenishment of filling.

A lever 16 has one end rigidly secured to the starting rod 17 and extends vertically therefrom on the outside of the loom frame 10. A connecting rod 18 is pivotally attached to the upper end of the lever 16 and connects the same with a crank arm 19 which is rigidly secured to the end of a rock shaft 20. The shaft 20 is journaled in the bearing 21 mounted on the loom frame 10 and in the brace 22 which is secured to the shaft 13 adjaoentits end. A collar 23 cooperates with the bearing 21 to prevent axial displacement of the shaft. An arm 24 depends from the outer end of the shaft 13 and supports a downwardly extending oli'set upright 25 which is adjustably secured to the arm 24 by means of a bolt 26 which fits into its split upper end.

A withdrawing member 27 is pivotally secured to the lower end of the upright 25 and is rendered adjustable by means of a slot 28 which is engaged by a bolt or pin 29. The withdrawing nuunber is offset and its ofl'set end is provided with a right angular, toothed extension 30 for engaging the filling end. A lever 31 is connected to the end of the rock shaft 20 and provided with anew largement at its upper end having a slot to receive the shaft. The slot 32 permits of movement transversely of the shaft 20 but does not permit rotational movement of the shaft withrespect to the lever 31, which must turn with the shaft. The lower end of the lever 31 is connected with the witlulrawing member 27 by means of a link 33 which is pivotally secured to the withdrawing member 27 and the lever 31.

In operation, when the filling replenishing, mechanism comes into operation, rotation of the starting rod 17 moves the lever 16 in the direction of the arrow in Figure 1, thereby rotating the rock shaft 20 and moving the lever 31 in the opposite direction from the movement of the lever 16. The lever 31 moves the withdrawing member downwardly into a substantially horizontal position, with the toothed portion 30 resting against the lay of the loom as shown in Figure 2. As the uill drops it falls over the withdrawing mem or, which is then pulled back to its normal substantially vertical position, as shown in Figure 3, when the filling replenishing operation is complete, and this return movement withdraws the filling end 34 and holds it in the position shown in Figure 3, until another quill of yarn runs out and the filling replenishing mechanism comes into action again.

It will be seen that I have provided a device which is entirel automatic, working in conjunction with t e filling replenishing mechanism, the only-time when'loose ends appear to be jerked back into the cloth, and is absolutely positive in action, without depending on the action of springs or the like.

While I have shown and described the preferred embodiment of my invention, it isto be understood that various changes in the size, shape, and arrangement of parts may be resorted to without departing from the spirit ofzmy invention or the scope of the subjoin'ed claims.

Having thus described my invention, what I claim and desire to protect by Letters Patent is:

1; The combination with a loom having filling replenishing mechanism including a starting rod, of a filling end withdrawing member, a rock shaft, a crank lever on said shaft, said crank lever having a slot to receive the shaft and permitting transverse movement of the lever relative to the shaft, a link connecting the crank lever and the withdrawing member, a crank arm on said rock shaft, a lever rigidly secured to the starting rod of the filling replenishing mechanism and having connection with the crank arm on the rock shaft, whereby rotation of the starting rod will lower the withdrawing member into the path of the falling quill, and whereby the return movement of the starting red at the completion of: the filling operation will return the withdrawing member to its normal position and withdraw the filling end.

2. In a loom having filling replenishing mechanism including a starting rod, a rock shaft journaled for rotation, a crank arm on said rock shaft, a lever rigidly secured to the starting rod of the filling replenishing mechanism, and connected with the crank arm on the rock shaft, a supporting arm secured to the transferrer shaft of the loom and depending therefrom, a filling end withdrawing member pivot-ally secured to said supporting arm and having an angular toothed etxension at its end, a crank lever seoured to the rock shaft for rotation therewith and having a slot allowing relative transverse movement between the rock shaft and crank lever, and means connecting said crank lever with the witlulrawing member. whereby rotation of the starting rod will lower the withdrawing member into the path of the falling quill, and whereby the return movement of the starting rod will return the withdrawingmember to its normal posh tion and withdraw the filling end from the shuttle.

3. In a loom having filling replenishing mechanismincluding a starting rod a rock shaft journaled for rotation, a c 'ank arm on said rock shaft, a lever rigidly secured to the starting rod of the filling replenishing mechanism andconnected with the crank arm on the rock shaft, a supporting arm adjustably secured to the transferrer shaft of the loom and de iiending therefrom, a filling end withdrawin; member pivotally and adjustably secured to said supporting arm, a crank lever secured to the rock shaft for rotation therewith, and a link tfUllllCtl ing said crank lever and witlnlrawing member, whereby rotation of the starting rod will lower the withdrawing member into the path of the falling quill, and whereby the return movement of the starting rod will return the withdrawing member to its normal position and withdraw the filling end.

In testimony whereof I atlix my signature.

WILLIAM MONROE TYSON.
